@ubdussamad I had accidentally misclicked a "h" in my keyring import so it wasn't grabbing the secret key. Works flawlessly now. Thanks! 😄
@GrantBirki Well, it's good that it worked out. That's why I don't use key rings for projects since they add extra margin of error. :) But sometimes it's just nessasary. I forgot the snippet can be considered under MIT licence.

@ubdussamad I took another look at my code and it looks like if I just use the yahoo pypi library I can authenticate with the credentials using keyring so that shouldn't be causing any issues. I also just printed the strings to standard output and did not see any whitespace or illegal characters. This is leading me to believe that the user agent is causing issues. I haven't done too many web requests in python. My system is running python 3.7 on windows but the desired goal is to run this script on a linux OS so I'm not 100% sure what user agent to be using but I will do some research. I will comment below if I find a solution to get the script running. Thanks!!
